To all whom it may concern:

Be it known that I, ALBERT REYNOLDS, a subject of the King of Great Britain, and resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Packaging-Machines, of which the follow ing is a specification.

My invention relates to machines for forming paper packages, filling the same with a given quantity of material and discharging the same. The object of my in- \rntlon is to provide a machine of the character indicated that will automatically and continuously form a succession of paper packages, place and compress the given quantity of material in each package, close the package and discharge the same. Other objects are to provide a machine of the character indicated that will be compact in highly efficient in its practical application.

The operation of the machine herein described is divided into three major movements, viz., the placing and packing of the material; the forming of the paper envelop around each charge of material formed and packed; the removal of the wrapped charge to a position for placing in a carton. These movements are, however, interdependent and cooperate to secure the desired results as herein described.

Referring more particularly to the drawings, 1 indicates a suitable hollow standard carrying a revolving cam member 2 and a table 3 supporting a frame 4 which in turn supports and positions the mold 5 and parts connected thereto. v

The placing of the material is effected as follows. The mold 5 communicates with supply chamber 6 through opening 7, the

sides of chamber 6 and operated by rod 9 extending through bearing 10 and provided with a terminal pin 11. At 12 is shown a bell crank pivoted at 13 upon a bracket 14 rigidly mounted upon the machine, the outer arm thereof having a-slot 15 formed thereln to slidably engage pin 11. The inner arm of hell crank 12 extends through slots 16 in supply chamber 6 and into molds 5 and is forked as at 17 to engage the opposlte sides of rack 18 operating in said mold, the said rack having vertical slots formed therein as at 19 for receiving forked arm portions 17 as shown. A head 20 is shown upon the lower end of rack 18 properly proportioned to slide freely in mold 5. These parts cooperate in such a manner that when the head 20 moves downwardly the upper ends of slots 19 engage portions 17 thereby operating bell crank 12 to withdraw plunger 8 to the position shown in Fig. 17 As the said head 20 approaches the end of its upward stroke the lower ends,- of slots 19 em gage the portions 17 thereby operating bell crank 12 ,to move plunger 8 to.the positlon shown in dotted lines in Fig. 17, whereby material dropped into chamber 6 is moved forward and caused to fall into mold where it is forced down by the next down- I ward movement of head 2 The head is reciprocated'through the medium of a rack' 18 in the following manner. At 21 is a pinion engaging rack 18 and mounted on shaftj22 revolving in bear ings 23 and carrying a second pinion 24. At 25 is a sector gear revolubly mounted at 26 and in permanent engagement with pinion 24. Sector 25 is provided with a pin-- ion 27 which is in permanent engagement with a pinion 28 revolubly mounted at 29 and carrying an arm 30. At 31 is a link connecting-arm with another arm 32, the latter being pivoted at 33 on a bracket 34 mounted on frame 4 and carrying a sector gear 35 engaging a rack 36 mounted to re. Rack 36 is offset at its lower end and provided with a ciprocate vertically as shown.

roller 37 adapted to engage the upper edge of cam member 2 and also the groove 38 formed in extension 39 thereon. The edge of cam member 2 opposite to groove 38 is formed as shown at 40 so that when the said cam member is revolved in thedirection indicated by the arrow the cam surface 40 40 and 40', force rack 36 upwardly thereby, moving link 31 downwardly and raising head 20 through the medium of the intervening gear connections. When cam member 2 revolves tothe point where roller 37 moves off of surface40 and engages groove 38 the rack 36 is drawn downwardly and, through the medium of r the several connections described, the head 20 is moved downwardly.

The movement, however, of head 20lis not uniform throughout its cycle of movement.

- it is drawn slightly upward by c'amsurface .IIIOVG After'the completion of its downward stroke 40 to assist in holding the paper firmly during the per-forating'process and then is by cam surface 40 to a point where its lower surface is flush with thelower end of mold 5 during the time required to fold the end of the aper thereover as hereinafter described. hen the folding of the end is completed the cam surface 40 comes into use and raises the head 20 up past the opening 7 from chamber v6.

he paper 43 from which the packages are made is fed in a continuous strip over roller 44 and thence over a pair of formers as '45 and 46 which causes the paper to freely envelop a little over three sides of the mold 5. The paper is brought into close andaccurate contact with these three sides of mold 5 by rollers 47 contacting there- With, mounted on 'pivots 48 on plate 49 sup ported on standard l'by means of rods 50, the said rollers being rendered'resilient by springs 51 inserted under projections 52 of brackets 53 in which said rollers are mounted. Upon the fourth side of mold 5 where the two side edges of pa er 43 are caused to approach each other, have mounted a seamer consisting of two parts, one part 54 being on bracket 55 set on plate 49, and the other part 56 on support 57 mounted on mold 5. These two members 54 and 56 have interlocking spaced fingers 58 and 59 respectively whereby the paper edges drawn therethrough are caused to overlap and form slidably mounted therein carrying pairs of rollers as 69-7 O-717 2 together with perforating knives 7 3 -7 47 5-7 6. These slidable members are forced inwardly a short distance to perforate the paper by means of.

small cams 65----666768 on the inner surface of cam member 2, and withdrawn by spring actuated arms 7 7-787 9-80 en'- gaging the same and pivoted upon arms as' 8182-83 84 projecting from plate 49.-

As shown in the present inventionthe perfforating knives 73-75 upon the wide side members 65 .67 are'stra'ight and positioned to perforatethe paper horizontally on each side of the tube'as at 85 midway between the rollers on ea'ch'member. The perforating 'knives 7476 on" the narrower end members 66-68 are-arranged to perforate the narrow s des of, the tube as-shown in Fig. 12;, the perforations at j-86being in line with the side perforations'at 85 and the angular'perforations 87-88-89-90 being along lines where the paper would naturally be ruptured upon folding in the longer sides.

After perforating the paper. the sliding members 65-6667--68 are successively moved forward over the package ends in the following order,-first 65 moves forward and is withdrawn and then 67 moves forward and is withdrawn, these two operations separating the paper along perforations 85--87'-8889 and 90 and folding the several parts as shown in Fig. 13. Next 66 moves forward and is withdrawn, its

/ withdrawal being closely followed by the advance .and withdrawal of member 68. These last two operations serving to sever the paper along the remaining perforated lines 86 and folding the freed parts over upon the package ends.

When the packages are made of paraffin paper and packed with heated goods, such as prunes fresh from a processor, no additional fastenin means for the folded parts is necessary. fiut when additional fastening means is required the member 67 is formed with a chamber 91 containing glue and suitable wicks as 92 are inserted in the side walls communicating with the chamber and so positioned that when member 67 moves forward a suitable amount of glue will be deposited upon the inner surfaces of the yet unbroken side walls of the tube so that when these walls are folded as shown they will overlap the side walls previously folded and securely seal them all in place. The members 656667-68 are moved forward as above described by suitable cams as 65"66"-67"68 formed on the inner surface of cam member 2 as shown and, of course, in different horizontal planes. They are withdrawn from the rolling operations by the same means that withdraws them from the perforating operations.

The com letedpackage must now be removed ready for placing in a suitable container or carton, and this operation is performed in the following manner.

The completed package is passed downwardly into passage 93 in standard 1, this passage being in alinement with mold 5 and spaced a distance therefrom sufficient to permit the passage of the rollers therebetween. In passage 93 is a vertically operating plunger 94 on rod 95 provided with a pin 96, the latter being slidably engaged.

by a lever 97 fulcrumed at 98. A link99 is pivotally connected at one end tolever 97 at 100 and at the other end to a lever 101 pivoted at 102 and pivotally connected to a vertically movable pin 103 at 104, the latter being mounted in bearing 105 in table 3. The upper end of pin 103 supports a roller 106 which operates on a cam surface 107 formed on the under side of cam member 2, this mechanism operating to raise and lower plunger 94 at stated periods hereinafter more fully set forth.

The completed package in passage 93 is removed, when the plunger 94 is in its lowest position, by means of a frame 108 in which it is deposited, the said frame being carried by an arm 109 pivoted at 110 and swinging in a horizontal plane. The mechanism for swinging arm 109 and form 108 consists of a lever 111 pivoted at 112 and slidably connected to a pin 113 on arm 114 formed integrally with arm 109. To the central portion of lever 111 is pivotally attached at 115 a link 116 pivotally connected at its other end 117 to one arm 118 of a bell crank pivoted at 119. The

portion 119 is in the form of a vertically positioned rod as shown and the other arm 120 also has a vertically extending pin 121 at its outer end adapted to engage cams 122123 formed on the under surface of cam member 2. As cam member 2 revolves cam 123 engages pin 121 and moves it inwardly thereby, through the mechanism described, moving form 108 into standard 1 and in alinement'with the passage 93 therein. Since plunger 94 is in a raised position at this time a slot 124 is formed in the form 108 so that the same can pass into the required position without striking rod 95 supporting said plunger 94. A further revolution of cam member 2 causes pin 121 to engage cam 122 thereby forcing the same outwardly and, through the mechanism described, swinging frame 108 outwardly to the position shown in Fig. 11 in which position it is in alinement with the opening 125 in the frame 126 forming a part of table'3.

The wrapped package must now be removed from the machine and placed in a carton. To effect this removal I provide a vertically movable rod 127 passing through the center of the pivoted end of arm 109 and forming a bearing therefor. The upper end of rod 127 is provided with a roller 128 engaging a cam 129 on the lower surface of cam member 2, and the lower end is provided with a laterally extending pin 130. Slidably engaging pin 130 and at one end thereof is a lever 131 pivotally mounted on a bracket 132 and slidably connected at its other end to a pin 133 on vertically movable rod 134 operating in bearing 135 in frame 126 forming a part of table 3. Rod 134i is axially alined with opening 125 in frame 126 and carries a head 136 substantially as shown. The position of the fulcrum for lever 131 insures the weight of the longer arm thereof maintaining the roller 128 in contact with cam 129 and normally positions plunger 136 in a lowered position as shown in dotted lines in Fig. 2. \Vhen however rod 127 is forced down by cam 129 the said plunger head 136 is forced up to a position flush with the top of table 3 so that the package is removed from the machine and inserted in a carton held over opening 125 ready to receive the same by a mechanism not shown. The opening 125 is normally closed by four gates 137-138-139-140 hinged to the side edges as indicated at 137-138 -139 -140 The upward movement. of the package automatically opens the gates upwardly so that they will open the folding parts of the carton end and permit the entrance of the package into the carton.

The cam member is revolubly mounted on standard 1 as clearly shown in Fig. 8

,In operation cam member 2 is driven in the direction indicated by the arrow in Fig.2 at auniform rate of speed, the several different cams preferably being formed integrally therewith.

Assuming a 'quantlty of material to have been deposited in chamber 6, the plunger 8 being ina withdrawn position as shown in- Fig. ,17. The operation of .cam 40 through parts 18 to 39 and 40 raises head I to a point above opening 7 at the same" time through parts 8 to 17 and 19'moving the material in chamber forward ere it falls into mold 5, the relative positions of 20 head 20, and plungers 8 and' 94 at this time being clearly shown" in- Fig. 18. Head 20 remains in a raised position during the revolution of cam surface 40 until the sur-' face 40 isireached whereupon it is moved downward to compression as shown in Fig. 19 withplunger 94 in the same position as.

shown in-Fig. 18. The downward movement of head 20 is continuous, and after descending a 1 given distance the bottom plunger 94 is also caused to move downward-1y a given distance with head 20 andthe two packages therebetween as shown in Fig. 20, by means of. cam surface 107 on cam 107 through parts 95- 406. Since each new package "is formed from a continuous strip of paper the downward movement of the filled package automatically draws down the" paper through folding devices 44-48 and 51-60 and forms a new section of paper tube of sufficient length that when out and folded it will form the ends of two packages.

At this time the newly filled package is held with the top surface of the material 45' therein flush'with the surface operated over by the lower rollers 69-70-71 -72 and the head20 is raised a'short distance by the cam surface 40? so that theside walls of the paper, tube will be held'taut during the perforating thereof. With the filled package and plunger 94 and head 20 in the position shown in Fig. 21 the four sliding members 6566 6768 simultaneously engage their respec-. tlve cams 65 -65 -65 -65 .and move for' ward and cause their respective knives to. perforate the paper ashereinbefore described and are immediately withdrawn as described.

Head 20 is now withdrawn by cam surface 40 to a point as shown in Fig. 22 so that its lower surface is flush with the lower surface of mold 5. This is instantly followed by the forward movement of member ac tuatedby cam 65 to sever and fold in one side of the paper tube, one-half over the rating operation member 2 has revolved through135 the filled ackage and one-half over the head 20. pon the withdrawal of member 65,

member 67 is moved forwardv actuated by forming an end for a new package over head 20 which is then withdrawn by the action of cam surface 40" to its highest position above opening 7.

The newly completed package is now moved upward to contact with and support the newly formed end of the next succeeding package as shown. in Fig. 18 by means of cam surface 107 on cam 107 and the next cycle of filling, forming and folding a package is begun. l

Upon the close of the downward movement of head 20 and plunger 94 the package previously formed and completed is placed in form 108 which has previously been moved into alinement with passage 93 by means of cam 122 and parts 109-12 1 operated there- I by. Immediately upon placing of the package in form 108 cam 123 operates thesame parts in an opposite direction to swing the package around to a position in alinement with opening 125 whereupon it is removed 7 as' hereinbefore described by the operation of cam 129 and parts 127 to 12s and 130.

In the cam graphs shown in- Figs.- 23 to 31 inclusive the several graphs are properly I positioned with relation to their several pe-; riods of operation, the zero line representing the time immediatel l v the time the cam.

perforating has been done, the folding has'been completed, thebottom plunger has just been withdrawn to its lowest point, th:-" no top plunger or head. 20 has almost reached preceding the perfo-.

its highest position, and plunger 8- is *just about to move forward to discharge the material in chamber 6 into mold 5.

It is understood of course that I. do not wishv to confine myselfto the specific form of the invention herein 'set forth but-to* include all changes in form, construction andmethod of operation included within the scope of the appended claims. Iclaim: 1 c
